SHEET-METAL ROOFING.

Application filed March 13, 1915. Serial No. 14,263.

To all whom it may concern:

Be it known that I, CHRISTOPHER B. ED- WARDS, a citizen of the United States of America, and a resident of Covington, in the county of Kenton and State of Kentucky, have invented a certain new and useful Improvement in Sheet-Metal Roofing, of which the following is a specification.

This invention relates to sheet metal roofing and more especially to the transverse joints made in the roof where the lower edges of the respective upper-sheets overlap the upper edges of the respective lowersheets, and the object of the invention herein is to provide an end-slip pocket or receptacle at the lower edge of each sheet to receive the upper edge of the next succeeding sheet below with the fastening nails driven through said lower edge of each upper-sheet just below the entrance of said pocket or receptacle so that the said nails are concealed beneath and covered by the upper edge of the next lower-sheet that is slipped into said pocket a suitable depth to assure a close fitting and non-leaking joint, the further details of which will be fully hereinafter described in connection with the accompanying drawings, in which- Figure l is a fore-edge perspective view of a roofing-sheet containing my invention, the upper end thereof being shown broken away in fragmentary-form from a somewhat larger fragment of the lower end, the latter end containing the essential pocket or receptacle feature of my device and including a lower-extension that is adapted to receive the fastening-nails; Fig. 2, a fragment of the lower portion of the sheet of metal used in making my form of roofing, such sheet being notched or cut into at its opposite sides in the manner required to form folds or bends along the two dotted-lines A and B: Fig. 3, a longitudinal-section showing the lower portion of the sheet containing my improved pocket or receptacle for the upper edge of the next succeeding lowersheet, the latter not being shown in this view and the upper end of the pocket-sheet being broken off and Fig. 4:, a viewsimilar to Fig. 3 but showing the upper edge of the lower-sheet duly pocketed or slipped into the receptacle provided in the lower edge a nail is shown driven through the lower extension of said upper-sheet.

1 indicates the body-portion of a roofing sheet having longitudinal crimps 2 and 3 along 1ts opposite side-edges as shown only in Fig. 1.

l indicates the upper end of the sheet and 5 the lower end thereof, both such ends belng of the same structure with the exception that the lower end, (see the blank-form seen in Fig. 2,) is cut away at 6, 6 in its side-edges a short distance upward from its extreme lower'edge and diagonal cuts 7 7, converging toward each other upwardly are made in said blank beginning at the inner upper corners of the cut-away notches or recesses 6, 6 and then the metal is bent forwardly along the transverse dotted-line B till it parallels with but does not touch the upper face of the lower portion 5 of the sheet, and then the metal is bent upwardly along the transverse dotted-line A till it contacts with the already folded portion of the sheet, whereby a pocket or receptacle 8 is provided that forms an end-slit for receiving the upper end 4: of the next sheet below and forming a lock-joint therewith. The crimps 2 and 3 at the sides are afterward made in the sheet and such crimps have space or pockets thereunder to receive the upper crimped ends of the next lower-sheet the same as the middle pocket H in the main portion of the sheet.

In Fig. 4; I have designated the lowersheet as 9 and numbered the fastening-nail as 10, the latter being driven into the lowerextension 5 at the points marked with the three crosses w, as, 00 shown in Fig. 1 but the upper end of the next lower-sheet is inserted or slipped into the pocket or receiving-slit 8 of the upper sheet.

The device is simple, easily and cheaply made and very readily applied. The fastening-nails are concealed beneath the upper end of each lower-sheet in the joint where the lap is made just ahead of the pocketportion of the sheet and provision is thus made to reduce leakage to the minimum. The upper-sheet prevents the nails from accidental withdrawal from fastening place and a smooth as well as neat finish results.

I claim A metal-roofing sheet having longitudinal crimps along its opposite edges, and a back- Patented May 25, 1915.-

wardly and forwardly extending underfold transverse joint between sheets and with the 10 made near the lower end thereof and with i'astening-nails dulv covered and concealed the plane body portion transversely notched by the said upper end of the said lowerand diagonally out out at its side-edges from sheet. v

- the said corrugated side-edges whereby a T 5 shallow transverse pocket is provided at the CHRISTOPHER ARDS' lower end of the sheet that is adaptedto re- Witnesses: ceive the upper end of the next succeeding JOHN ELIAs JONES, lower-sheet in making a ready end-slip BERL RIGDON.
